Earlier this week, actor Charles Esten visited patients, families and caregivers at two Las Vegas hospitals through Musicians on Call, a non-profit organization that brings live and recorded music to the bedsides of recovering patients.

“It’s just genius because music does bring healing," Esten said in an interview with Musicians On Call. "Music does bring peace. It can bring laughter. It can bring joy. It’s almost like a medicine that is mainlined almost directly into the places that it’s needed the most, directly into those hospital rooms."

One of the victims he serenaded was Tina Frost, a big fan of his show. Frost was attending the Route 91 Harvest Festival with her boyfriend and some friends when the bullet pierced her right eye and traveled to her brain.

“She is going to be so excited when she sees the autograph,” a post on her GoFundMe wrote. “She records the show every week.”

Esten was also joined by country acts the Railers and Filmore during his visit to the hospitals.

“They are in the darkest of situations,” Cassandra Lawson of the Railers said. “I want to hug them and cry with them, but to know that we’re changing families’ lives one room at a time is so overwhelmingly awesome and humbling.”
